VALVE.

Thisinventionirelates t-o valves broadly,

1nd more particularly toa valve whichmay vbe utilized for reducing flow-pressure fromv vided with a series of spaced openings, exit through such openings from such sta-nds-7 being` regulated by a series of slide valves.'-

The stands are ordinarily open atthe top and ditches are dug in theorchardy for the purpose of conducting water from such exitportions of the stands under control ofy such valves during an irrigation of the or-K chard. Very few of the Aslide valvesy are water tight and there is a constant seepage of wat-er between the valve seats andthe gates thereof. It isA highly. essential vin this type of stand to produce .a volume flow without undue pressure, for the reason that water under. pressure will of course wear away the earth and deepen the ditch, 'aswell as pack the earth, which is undesirable,as it prevents ready penetration of water into the ground. An objectof this invention is therefore to produce a volume flow of water without undue pressure ysufficient' to vwear away or out away earth and still prevent anyr leakage of water to the various ditches when the valves are properlyturned to cut flow of water to such ditches.l

Other objects ofthe invention will appear as the description of thel invention proceeds. :f

' lVith the above and other objects in view, the invention consists in the novel arrangement of the various parts, members and features, as disclosed in one of its embodiments in the accompanying drawing, described generally and finally pointed out in claims.

In the drawing:

Figure l is a fragmentary cross sectional elevation of a. stand, a main conduit, the improved valve being associated with the rstand for conducting water vfrom the stand to ditches in the earth, said earth being shown surrounding the main conduit and a portion of thel stand;

Figure 2 is a fragmentary detail on an enlarged scale from that of Figure 1,showa part ofthe stand and a modified ferm of valve casing;

`Figure 3 is `a vertical'elevation onan enlarged scale,fof the valve; and,

VACorresponding'parts in all the figures are designated by the same reference, characters.

Referring with particularity to the drawing a unit valve controlsystem as depicted inFigurel is designated Ls an entirety by A, and of such unit system a is a main conduit for the conducting of a fluid, Asuch as water, to a stand b .with 4a valve'or valves c yassociated with the stand for conducting water within such stand to points of :distribution. The conduit a maybe sunk beneath the surface-of. earth .formation e, and it is to be noted that thestand b is likewise surrounded in part by such earth. formation e. Normally the stand b is filled with vwater when the conduit a has been filledvor has flowing water` ther-ein, and flow from such stand is accommodated through the valves c, the valves c in turn having pipes associated therewith, if desired, leading to furrows orditches in the earth formation e. In the showing, however, water from the stand b is conducted through the valvesandy allowed to escape through valve outlet-ports or members and then-,dropped to the earthinto 'the furrows or ditches. Ordinarily, as stated. the stand would belopen atthetop anda series of'transverse ports `would be formed in such standf with the exit'from such ports controlled bymeans of slide valves. However, inthe present instance the stand is'gprovided-with a top or cover d whichmay be detachably placed thereon or as shown integrally r`formed withV ing f having. a part formed with a bore l' termed the intake orifice, and with a bore 2 substantially at right angles although not necessarily so, tothe `first orifice l, which orifice 2 is termed the4 outlet orifice. The

casing f is provided. with shoulder or valve.

i seque-.nee .the pressure flow oi! water/or other seat portion 3 and likewise' said casing in alignment with the axis ot such orifice l, is bored and threaded as shown at 4l tor reception of a valve member 5., which valve in-e. cludes a shank 6 carrying a screw-threaded' enlarged portion 7 adapted for screw-thread ed engagement with the threaded portion 4l oi' the casing, and which' shank.. is transv versely slotted as shown at 8. Furthermore, the said shfank is provided' with' a' head 9 adapted to carry a washer Y10,whieh washer is 'held tothe part 9 by rueans 'eta .bolt ll. ylflhe valve likewise is provided wi'tha handle l2 whereby said valve Aiii-ay be turned, and itis to be noted that upon a turningV of such valve the gasket or washer l0 ina'y seated uponthe-valve seat on shoulder 3.. A c'yli-ndrical valve chain'ler 13', within' whi'clrthe valve operates and likewise winch .permits 13 and then through the slot' produced in the shank 5 of. such valve. The water or other fluid is then allowed to escape from' the chamber through the outlet orifice 2. It will be .noted lthat the gasket 10 acts as a baili'enieiiiber for initially bu'lling the water,

The water in its flow, in a measure, forms an eddy in the slot 8 of the shank. `In other words, the cross sectional area ineluded between the inner surface wall of the chamber and the periphery ot the head and .gasket or washer l0, is less than thev crosssectional area immediately above suchliead` 9," and as a confluid is reduced, the volume lof the ilow oi' water remaining substantially. the saine. It ini'ght be said thatl this particular' torni ot valve provideszones ot high pressure, and olt lreduced pressurato produce a. volume li'ow ot fluid passed through the valve.

Figure 2 shows an adaptation of the valve to an opening in :the side of the sta-nd l), the vprinciI'J-le oi the valve, however, `remainingthe same. Tater will till ,the.sta.nd7 b, then flow outwa'rdli7 "frein sueli"tnd through outlet orifices at the will and control ot the operator. Obviously troni the construction showndripping and llow ot water when not needed is prevented.
